Including 3rd party libraries

sepbot — Thu, 19 Dec 2013 06:56:40 GMT

I have some 3rd party libraries that I use with an application that I am currently developing. These libraries are not present in the Virgo repos of the controller. Unfortunately there are no OSGi bundles available that I can deploy to be consumed by my application either. So, how can I go about adding 3rd party libraries to the Virgo repos?

I have tried placing the .jar files and all dependencies in the watched directory of Virgo, however when I try to upload my application to the controller, I get a dependencies failed error message and the application remains in staged state.

As per HP VAN SDN Controller Admin Guide document if an application is in staged state , the application can be installed [ page 15].

Alternately you can try Application Manager Actions using cURL commands[ page 77].

Hope this helps.

Tried that once - you need to convert library jar file into OSGi bundle before you place it in your virgo repository on controller. There are ways to make this conversion, search Internet. Then, if dependencies are correct in POM file of your application (if you use Maven) it should work for you.

Btw. what is what you need to add that is missing?

It was just some Apache related support libraries. I ended up making a new repository in Virgo and putting my libraries and their dependencies in there. In my case, I had to include several libraries, so I took this approach. However, if it is only one or two libraries that need to be included, you can use <Export-Package> option of Maven Bundle Plugin.

Hi Sepbot,

Consolidating all the approaches to deploy a third party jar file for the application as below-

First approach:

1) Include the dependency for third party library in maven. This will make the build successful.

<groupId>org.erlang.otp</groupId>

<artifactId>jinterface</artifactId>

</dependency>

</dependencies>

2) Export the thirdparty package you want to use.

<build>

<groupId>org.apache.felix</groupId>

<artifactId>maven-bundle-plugin</artifactId>

<Export-Package>

com.ericsson.otp.erlang.*

</Export-Package>

</instructions>

</configuration>

</plugin>

</plugins>

</build>

Second approach:

1) Convert the third party jar file into osgi bundle

2) Add the bundle to application zip file by editing the pom.xml in xx-app directory

3) Edit plan file in xx-app directory to add the new bundle

Third approach:

1) Create a new repository under opt/sdn/virgo/repository

2) Edit org.eclipse.virgo.repository.properties to specify new repo

3) Convert third party jar files into osgi bundles and deploy them into the new repo through virgo admin console
